SUBJECT INDEX 



The Compilation of Experimental Work in Part IV contains prac- 

 tically everything known about the subjects and is arranged alpha- 

 betically, with subheads in logical sequence, in index form. The main 

 topics are given with page numbers in the Index but the subheads 

 (italicized in text) are indexed only when not included in a main 

 topic. Subheads under "Cleavage" and "Respiration" are arranged 

 alphabetically in the text and "Respiration" has a special index to 

 various factors influencing metabolism (p. 212). Many substances 

 not listed in the Index may be found under these main topics, and 

 also under "Parthenogenesis." 



References to "Other Species" occur at the end of each topic. These 

 species are not indexed individually.
